Question

Find the Area of the figure below, composed of a rectangle and two

semicircles. Round to the nearest tenths place.
13
10

Answer 1

`208.5 \: {units}^(2)`

Explanation:

Area of the figure = Area of rectangle with dimensions 13 by 10 units + Two times the area of one semicircle with radius (10/2 = 5) 5 units.

`= lb + 2 * (1)/(2) \pi {r}^(2) \\ = 13 * 10 + 3.14 {(5)}^(2) \\ = 130 + 3.14 * 25 \\ = 130 + 78.5 \\ = 208.5 \: {units}^(2)`
